Filter by:Early diagnosis and appropriate treatment for COPD subjects are both critical to minimize the progression of COPD and improve outcomes. Also, evidence suggests that high eosinophil (specific type of white blood cell that protects body against certain kinds of germs) level is associated with increased risk of both moderate and severe exacerbations in COPD subjects. To date, there is insufficient amount of data that describes the prevalence of COPD in Brazilian primary care units. Thus, this multicenter, cross-sectional study conducted in five centers located in five different Brazilian cities will provide estimation about the prevalence of COPD in primary care and will also determine the levels of eosinophils in subjects with confirmed COPD diagnosis. Approximately 2,500 eligible subjects are expected to be enrolled in the study.
Patients with interstitial lung disease (ILD) experience distressing activity-related respiratory discomfort which is challenging to manage therapeutically. Interventions such as pulmonary rehabilitation, collaborative self-management, supplemental oxygen therapy and oral opiate medications, are variably effective and therapeutic responses to each in individual patients are difficult to predict. The purpose of this study is to evaluate the acute effects of inhaled opiate therapy (fentanyl citrate) on breathing discomfort (dyspnea) in individuals with mild-to-moderate ILD, as well as examine the potential mechanisms of dyspnea relief.
Inspiratory muscle training（IMT）was an rehabilitation therapy for stable patients with chronic obstructive pulmonary disease(COPD). However, its therapeutic effect remains undefined due to unclear of diaphragmatic mobilization during IMT. Diaphragmatic mobilization represented by transdiaphragmatic pressure（Pdi）and neural respiratory drive expressed as corrective root-mean-square(RMS) of diaphragmatic electromyogram(EMGdi) provide vital information to select the proper IMT device and loads in COPD, therefore make curative effect of IMT clarity. Pdi and RMS of diaphragmatic electromyogram (RMSdi%) was respectively measured and compared during inspiratory resistive training and threshold load training in stable patients of COPD.
Asthma is a chronic inflammatory disease of the Airways of recurring character. The obstruction to the airflow carries the short-and long-term consequences that require prophylactic interventions and in emergency many times. The children due to immaturity of the respiratory system associated with the use of steroids suffer structural consequences, as for example, the physical deconditioning that intensifies the symptoms of the disease and affects negatively on the quality of life. Therefore, to set up a physical training program suitable for the paediatric population, using resources to increase adherence to the regular practice of exercises, can be the difference for the reduction of the number of exacerbations, the sensation of Dyspnea and the doses of medication, positively impacting the clinical picture of child asthmatic. The investigators conducted a randomized, blinded in order to evaluate the effects of training with active video game associated with resisted exercise the exercise in inflammatory and functional outcomes resisted in asthmatic children.
The purpose of this study is to learn more about new noninvasive ways of detecting lung disease in US Military personnel and people who worked as contractors during military operations in Iraq and Afghanistan. This study is looking at conducting a type of breathing test called the lung clearance index (LCI) test which is being investigated as a potential noninvasive way to detect the type of lung disease that may be seen in symptomatic deployers retuning from Iraq and Afghanistan.
The aim of this study is to test whether aspirin improves endothelial function in alpha-1 antitrypsin deficiency-associated lung disease, measured by pulmonary microvascular blood flow on magnetic resonance imaging (MRI) and with apoptotic endothelial microparticles.
Pseudomonas aeruginosa (PA ) is associated with chronic lung infections in patients with chronic obstructive pulmonary disease (COPD). Commensal flora (microbiota) in lung was recently described using high-throughput sequencing techniques (NGS). PA strains isolated during lung infection episodes of severe COPD patients often show resistance to antibiotics including imipenem that is mainly due to mutation in oprD. In collaboration with Harvard Medical School, the investigators have recently demonstrated that PA OprD mutant shows increased survival (fitness) and its virulence. This bacterium could be more likely to colonize. Colonization by PA OprD mutant could influence the pulmonary microbiota and may worsen disease evolution, particularly in terms of frequency of exacerbations. Our objective is to describe modification of pulmonary microbiota associated with PA colonization, including OprD PA mutant, in severe COPD patients. The investigators will correlate the microbiota modification to medical history. Stable severe COPD patients will be included. Three groups of patients will be sampled: 1) not PA colonized, 2) PA colonized and 3) PA OprD mutant colonized. Medical history will be recorded by the physician as usual and three samples will be performed: 1) sputum, 2) oral wash and 3) water used for oral wash. Regular bacterial culture will be performed and NGS will be performed also to characterize the microbiota.
The purpose of this study is to assess the feasibility and the reliability of a telemonitoring system during pulmonary rehabilitation in patients with chronicle obstructive pulmonary disease. The feasibility is assessed using the patient's satisfaction and it ease of use. The reliability of the remote telemonitoring system is assessed comparing the local data (extracted from the monitoring device itself) and the data transmitted through the telemonitoring platform.
The aim of the study is to determine if increased retrograde shear would further deteriorate the already impaired vascular function in severe COPD patients.
The aim of the current study is to investigate the efficacy and safety of nintedanib over 52 weeks in patients with Progressive Fibrosing Interstitial Lung Disease (PF-ILD) defined as patients who present with features of diffuse fibrosing lung disease of >10% extent on high-resolution computed tomography (HRCT) and whose lung function and respiratory symptoms or chest imaging have worsened despite treatment with unapproved medications used in clinical practice to treat ILD. There is currently no efficacious treatment available for PF-ILD. Based on its efficacy and safety in Idiopathic Pulmonary Fibrosis (IPF), it is anticipated that Nintedanib will be a new treatment option for patients with PF-ILD.
